1 Yes Distal equivalent dendrite Glutamate Neocortical Superficial Pyramidal Neuron terminals (T) and Thalamic Relay Neuron terminals (T) From cerebral cortex
2 Yes Distal equivalent dendrite D1 Substantia Nigra Dopaminergic Cell terminals (T) Input from dopaminergic neurons in the substantia nigra; causes small depolarization? sometimes a decrease in firing rate; modulates anomalous rectification of dendritic membrane (I IR)?
3 Yes Middle equivalent dendrite Glutamate Neocortical Superficial Pyramidal Neuron terminals (T) and Thalamic Relay Neuron terminals (T) From cerebral cortex
4 Yes Middle equivalent dendrite D1 Substantia Nigra Dopaminergic Cell terminals (T) Input from dopaminergic neurons in the substantia nigra; causes small depolarization? sometimes a decrease in firing rate; modulates anomalous rectification of dendritic membrane (I IR)?
5 Yes Proximal equivalent dendrite Glutamate Neocortical Superficial Pyramidal Neuron terminals (T) and Thalamic Relay Neuron terminals (T) From cerebral cortex
6 Yes Proximal equivalent dendrite D1 Substantia Nigra Dopaminergic Cell terminals (T) Input from dopaminergic neurons in the substantia nigra; causes small depolarization? sometimes a decrease in firing rate; modulates anomalous rectification of dendritic membrane (I IR)?
7 Yes Soma D1 Recordings in slices showed that D1 receptor activation can either inhibit or enhance evoked activity, depending on the level of membrane depolarization, by modulating an L-type Ca2+ conductance
8 Yes Soma D2 Activation of both D1- and D2-class receptors has been shown to modulate potassium and sodium currents in acutely isolated neostriatal neurons
9 Yes Soma Gaba GABAergic responses evoked by electrical stimulations have been studied in slices
10 Yes Soma Muscarinic Recording from dissociated neurons using intracellular and whole-cell voltage-clamp recordings showed that carbachol can act at M1-like muscarinic receptors to reduce the membrane K+ conductances and excite the neostriatal neurons
 Neuronal Currents (20)

1 Yes Soma I K
2 Yes Soma I Na,t Kinetic properties were studied using the whole-cell patch-clamp technique
3 Yes Distal equivalent dendrite I h Large EPSPs activate I IR, increasing the membrane resistance, shortening the dendrites electrotonically, making the cell more sensitive to subsequent inputs (see
4 Yes Middle equivalent dendrite I h Large EPSPs activate I IR, increasing the membrane resistance, shortening the dendrites electrotonically, making the cell more sensitive to subsequent inputs (see
5 Yes Proximal equivalent dendrite I h Large EPSPs activate I IR, increasing the membrane resistance, shortening the dendrites electrotonically, making the cell more sensitive to subsequent inputs (see
6 Yes Axon hillock I K
7 Yes Axon hillock I Na,t
8 Yes Axon terminal I N
9 Yes I L high threshold
10 Yes Soma I L high threshold However, recordings in slices showed that D1 receptor activation can either inhibit or enhance evoked activity, depending on the level of membrane depolarization, by modulating an L-type Ca2+ conductance
11 Yes Soma I N Whole-cell voltage-clamp recordings showed that HVA currents were present in at least 95% of neostriatal neurons, but that the majority of them appeared to belong neither to the "L-type" nor the "N-type" classification
12 Yes Soma I T low threshold Another study suggested that adult neostriatal projection neurons do not express significant levels of LVA Ca2+ current
13 Yes Soma I A A slowly inactivating A current has also been studied
14 Yes Soma I h The contribution of an inwardly rectifying current (IKir) were studied in slices. The results suggest that the hyperpolarized state is determined principally by this current
15 Yes Soma I Potassium A non-inactivating, Ca-independent, K+ current may limit the amplitude of membrane depolarizations associated with prolonged excursions into the depolarized state
16 Yes Soma I Calcium Whole cell recordings from acutely dissociated neurons exhibited a R-type currents that were characterized as HVA by their rapid deactivation kinetics, half-activation and half-inactivation voltages, and sensitivity to depolarized holding potentials. In neocortical pyramidal neurons these currents inactivated at more negative potentials than in medium spiny neurons
17 Yes Soma I K,Ca Calcium-dependent potassium channels are preferentially activated by calcium entry through N- and Q-type channels
18 Yes Soma I N Calcium-dependent potassium channels are preferentially activated by calcium entry through N- and Q-type channels
19 Yes Soma I p,q Calcium-dependent potassium channels are preferentially activated by calcium entry through N- and Q-type channels
20 Yes Soma I Na,p Nomarski optics and infrared videomicroscopy were used to demonstrate the existence of a TTX-sensitive persistent Na+ conductance (INaP) in identified medium-sized neostriatal neurons
